Differences in verbal memory performance in postmenopausal women receiving hormone therapy: 17β-estradiol versus conjugated equine estrogens

Rasgon, Natalie L.
Objective: Much controversy exists and many questions remain unanswered about the effects of hormone therapy (HT) on cognition in postmenopausal women. There is growing evidence suggesting that HT compounds containing conjugated equine estrogen (CEE) have negative effects on cognition whereas 17β-estradiol (17β-E) either has positive or neutral effects. The present study sought to further examine […]
Study of the effects of vinpocetin on cognitive functions
Introduction: Chronic cerebral hypoperfusion is a risk factor for the development of certain types of dementia. Mild cognitive impairment is a stage of predementia condition, because the symptoms are similar but not as severe as the symptoms in patients with dementia. Vinpocetine, due to its complex mechanism of action, has an important role in the […]

Age-related changes in nutritional status can play an important role in brain functioning. Specific nutrient deficiencies in the elderly may exacerbate pathological processes in the brain. Consequently, the potential of nutritional intervention to prevent or delay cognitive impairment and the development of dementia is an important topic. A randomized, double-blind, placebo-controlled trial has been performed […]
